RADIATOR HANGER.

Application filed. April 21, y192.3. Serial No. 633,602.

My invention relates to an improved form ot radiator hanger forsupporting radiators used for heating purposes from the wall of abuilding.

As is wellA known in the art, difficulty is frequently experienced insupporting radi-- ators used for heating purposes which are of the walltype` on account ot the various spacings or' the radiator elements andthe further tact that there is no relationship whatever between theparts of the wall to which the tastenings must be secured, for example,the ordinary studding in a plastered wall, and the portions of theradiator to which the tastcning devices must be applied. Difficulty isalso experienced in this connection requently as a result of the pipeconnections, installed in the building' at the time of its erection, notbeing exactly spaced from the walls: as a. result of which in mountingone radiatorit may be necessary to place it a certain distance from the"all and in mounting a second Vradiator it may be necessary to place itat a different dista-nce from the wall. Diliiculty is also experiencedin ,conL nection with mounting radiators as alcove described in soaccurately locating the mounting devices vertically that the radiatorwill be at exactly the desired height when placed on the mountingdevices.

By my invention I provide a form of radiator mounting'mechanism by whichthe bases ot the mounting devices may be vsecured to the wall in advanceof installing the radiators and, it desired, while the building is inconstruction, the bases being secured to the parts of the wall, forexample, the studding, that are best adapted to supporty the bases andas long as the bases are mounted on the wall within the outer boundariesof the radiators to be supportedrthereby, the radiators may subsequentlybe mounted on the bases in desired position. inasmuch as my improvedmounting devices provide for ver'- tical adjustment ot the radiator.supports on the bases, they provide also ,tor adjustment of theradiator supports on the bases towards and away from the surfaceA of thewall, and

ever inay be the spacing ot its vertical elements, to hold the upperportion of the radiator securely in place, the said devices beingadjustable relatively to each other, so that in any case the radiatormay be mounted in a vertical plane or parallel with the face-of thewall. A further advantage secured by my mounting devices is that ltheyare entirely concealed behind the radiator with the excep tion oi themounting arms extending underneath the bottom thereof, and they are thinenough in their entirety so that the radiator may be mounted as close tothe wall as desirable operating conditions of the radiator will permit.Y

My improved mounting devices are further adapted to .support wallradiators ot different types, for example cast iion wall radiators ofvarious uesigns and constructions and also pipe coil radiators.

My invention will best be understood by reference to the accompanyingdrawings showing preferred embodiments thereof, in which- Fig. l shows apair of radiator supports in front elevation with a radiator illustratedin light lines supported thereon,

then thc bases 15 are secured to a wall as described, it frequentlydevelops that the radiator must be supported somewhat farther from thewall than provided for by the thickness of the base 15 and the thicloness of the vertical portion vof the bracket 16. To accomplish this thearm 16h may be moved outwardly from the base 15 and l eld in saidposition by an adjusting screw 21- extending through its lower portionand engaging the base 15. The length of the vcrtical portion of thebracket 16 is preferably so taken that for any adjustment of the arm 16baway from the wall, the supporting surfaces 16c will still elfectivelyengage the bottom of the radiator to positively retain vit againstmovement towards or away from the wall unless the radiator is raisedbodily from the arms 16".

Each of the upper clamping mechanisms 18 consists in part of a` screw orbolt 25 eX- tending through one of the apertures of the radiator andprovided with a washer 26 at its head end and a nut 27 adjacent the rearface of the radiator, the nut and washer serving to positively engagethe radiator and secure the bolt thereto. The remaining parts of eachclamping mechanism 18 are better illustrated in Figs. 8 and 9 and asshown in said figures, said parts comprise a circular disc 18V of adiameter slightly less than the width betweenthe inner surfaces of theguideways of the base 15, a washer 18h of a diameter slightly less thanthe distance between-the inner edges of the flanges 15a of the base 15and an arm 18C, said parts being securely held together by a rivet 18dor equivalent fastening device. The washer 18h is of substantially thethickness of the metal of the base 15 and the mounting mechanism is thusadapted to be placed upon and retained by the flanges 15a which preventdisplacementof the mounting means 18 towards or away from the wall 23.The construction howeverv provides that the mounting' means 18 may bemoved vertically on the base 15 and that the arm 18C may be turned forany` position vertically ofthe mounting means on the base 15', asdesired. The outer end of the arm 18C is provided with threaded end of asleeve 18e which is internally threaded to receive the end of the bolt25, the length of thek sleeve 18e being pret'- ings providing' athreaded opening receiving ythe' erably sutl'ic-ient to permit asubstantial amount of adjustment of the bolt 25 towards or away from thewall 23 in the sleeve. The distance between the threaded bore of thesleeve 18e and the center of the disc 18L is preferably at least half ofthe maximum spacing of the apertures in t-he radiators that are to besupported by the mounting devices, as a result of which, whatever may bethe position of the radiator on the arms 16h, the arms 18c may be swungabout the centers of the discs 18 to bring the sleeves 18e intoalignment with the centers of the apertures through the radiator throughwhich the bolts 25 extend. ln securing the upper portion of the radiatorin desired position by means of the mounting means 18, the bolt isturned in the nut 27 until the radiator is in desired vertical positionwith the end of the bolt rest-ing against the end of the sleeve 18C butbefore there is engagement between the threads of the bolt and thethreads of the sleeve. The bolt is then turned in the nut 27 and in thethreads in the sleeve 18 until a clamping engagement of the washer andnut 27 is secured with the radiator, for which condition the samespacing will remain between the nut 27 and the end of the sleeve`18c asthat occurring at the beginnii'ig of the turning of the bolt in thesleeve 18. lVhen this is done all of the parts ot' the clampingmechanism 18 are positively held against accidental displacement and theupper portion of the radiatei'V is positively supported in desiredvertical position. 'lhe sleeve 18e may be conveniently made of a lengthpermitting its reversal in the arm 18, the relation of the parts shownin Figs. 8 and 9 of the drawfor the closest possible adjustment of theradiator to the wall permitted by the base 15 and a reversed relationot' the sleeve 18e in the arm 18C proif'iding for a correspondinglyincreased and maximum spacing of the radiator from the wall. Obviouslyany desired spacing of the radiator from the wall may be secured bymening the bolts 25 and sleeves 18e of corresponding length and bymaking the screws 2T. of corresponding length. y

From the above it will be observed that my mounting means provides forvertical adjustment of the radiator as may be required for anyparticular case even though the bases are secured to the wall betere theenact vertical position of the radiator is determined; that they alsoprovide for adjustnient of the radiator laterally on the mounting meansas may be required by the pipe connections and that they further providefor adjustment of the radiator towards or away 'from the wall and formaintaining the vradiator in vertical position in any ladjustmentrelatively to the wall. lt will further be observed that the mountingmeans 1s rigid llt) and el substantial emistraction and tnrthermore thatit is et ininiuunu thickness to secure the results iinlicaled, the onlyTreduiremeuts being that the metal ot the base shall be :wullicicutllYthielc. tor example one eighth et au inch.` to eive anlple stabilityand. strength (o the bare and that` the guideuays need only to be etsutlicient depth t'o insure that the truuuions tti and brachel lli shallhave :uuple stability and strength. ln practice the bracket lli univ beeither a casting or a l'orgriugr and tinil a desirable ctmstruction tobe a etc-el 'toastingl on account et this allerdingg a niaxilnmu etstrength with a iuiuiiuuni thickness et the ln'aclet.
